A layer of the Near Umbra associated with ideas, abstract thinking & human concerns. Also called the Astral Umbra, Astral Plane & Astral Space. Most mages visit this layer of the Near Umbra unless they try to reach another. Shamans & other mages with a more natural, elemental outlook gravitate towards the Middle Umbra.
Must travel through Spires to leave Vulgate and reach Umbral Courts and other higher realms. Vulgate changes between visits but doesn't alter that much to suit individual visitors. Epiphamies are a higher, more distant part of the High Umbra and appear differently based on who visits them and their goals, state of mind, etc. Time spent in most Epiphamies is zero or very short. Revised Edition in Infinite Tapestry pulled the River of Language down to the Vulgate & made it the entire Vulgate.
